Question to do with orbital motions (prograde and retrograde)

Suppose Jupiter and venus appear very close to each other in the sky. If Venus is at maximum elongation, Jupiter would be moving in prograde motion.

I dont see how jupiter and venus can be in conjunction while venus is at its maximum elongation.

I also dont understand how, with these conditions, there is a definate "prograde" or "retrograde" answer. Isnt it a bit ambiguous given there are two maximum elongation points?

I just dont understand.

Orbiting plan for satellites πŸ›° around Venus - prograde or retrograde?

You’ve been named Orbit Master of Venus: you can decide the rules of satellites in orbit for Venus. Do you / we decide to set it that they go prograde (following the direction of the sun) or following the natural spin of the planet (retrograde)? What are the advantages and draw backs of each direction? Does it matter?

The Sun orbits a black hole in the middle of the Milky Way. Does the Earth’s North Pole point roughly prograde or roughly retrograde on that orbit

I tried googling everything I could think of, but it didn’t come up with anything relevant.

Rephrase of the question: are we chasing Polaris, or is Polaris chasing us?

Edit: okay, so the sun orbits the barycentre of the Milky Way galaxy, no problem.

Is there a mod that allows you to change SAS type (Prograde, Retrograde, etc.) from a hotbar?

I like to play the game from IVA view as much as possible, and it bothers me that I have to go into the map view to change my SAS type. Some parts have IVA controls for this, but if there were a toolbar then all IVA views would work.

I think the artificial horizon script should also show where your retrograde vector is, just like it does with your prograde vector here. This would be very useful on ships that have very low backward thrust compared to its forward thrust.

Retrograde vs Prograde and Other things

Star Citizen could look at KSP for some inspiration.

In the Cockpit we could use a prograde and retrograde indicator to let us know how our ship is orientated in regards to its velocity. This is especially useful when flying uncoupled

Another thing KSP does well is the velocity indicator. Our speed should be displayed relative to whatever we have targeted. It makes a lot of sense especially in space.

Really wish there was an autopilot toggle for 'keep to horizon' like there is for prograde and retrograde

speaks for itself... i wish my kerbal or flight computer could be set to just keep my aircraft's trim adjusted so that when I just set that bitch to full throttle and get to an altitude that I like, it would just stay pointed at horizon so that I can physics warp for a while while I go mix a drink or whatever and then come back to a jet that has made it a considerable distance around kerbin. long jet flights in atmo get pretty tedious, and a horizon-hold, or rather just an altitude hold for autopilot like in any modern aircraft, would be great.

[poll] is the Prograde/retrograde mark Yellow or Green ?

So, on a KSP discord server i'm on, we've been debating about this for quite some times.
We can't figure out if the Retrograde/prograde marks in the map (when you create a maneuver node) are green or yellow. So we had the idea to ask the community and pick the color that the majority sees as a basis.
So please answer this poll, thank you !

"Target" Prograde and Retrograde?

So, in attempting to complete the Career mission of rescuing the Kerbonaut stuck in orbit around Kerbin, I used this guide on getting a rendezvous, which worked, though I'm not sure why...

So my question is on what the navball is actually showing when you're in "target" mode, but both you and the target are orbiting something else: I can understand the pink markers pointing directly at and directly away from your indicated target, but what are "prograde" and "retrograde" in that context? I'm not orbiting my target, so what are those indicators representing?

In the tutorial video, you burn toward the target (pink) to get closer, but burn retrograde (green; not pink) to kill relative velocity. Why are they not a matched set (either both green or both pink)? Is the answer real-life physics, or a game-mechanic-thing? Thanks!

Are there systems with exoplanets that don't orbit on the ecliptic? How about both prograde and retrograde?

I know that our solar system has a few outliers (Pluto's orbit prompted this question), but for the most part, our planets are within 1 to 6 degrees of the ecliptic. Have there been other systems discovered that do not do this?

I'm also interested to learn if there are systems that have large planets orbiting both prograde and retrograde. I know that all of our planets are prograde (and if I remember right, everything but comets) - but it seems like there certainly has to be an oddball system out there.

Prograde and retrograde reversed?

Hadn't played in a while so I hopped back on after the major update, but there's something very odd going on with retrograde and prograde indicators on the Navball... they're reversed! Even more odd is that when I set a maneuver, it's advising that I burn in the wrong directions too!

Anyone else encountering this?

Q: Uh my satellites prograde is actually retrograde... what the what?

Hi,

I was doing some mechjeb maneuvers to circularize my satelite's orbit and I noticed it was burning in the opposite way than I was expecting. I have no idea what caused this.. maybe because placing a satellite on top of the command modules nose reverses something internally...?

Which polar orbit is prograde and which is retrograde?

It's easy to say it about equatorial salellite orbits - satellite moving eastwards has prograde orbit and satellite moving westwards has retrograde orbit (and I think that such satellites pretty rare if these exist at all). But what about polar orbits? How to distinguish between prograde and retrograde orbit? Only using distant stars as the frame of reference? Or is there any other (maybe even preferable) way to distinguish between two opposite directions of polar orbits?

Lock steering to prograde/retrograde not "aggressive" enough

I'm working on a script to automatically deploy a satellite into a variable orbit with variable precision. It kinda works, but it's extremely inefficient due to the kOS autopilot not correctly locking steering. When commanded to point retrograde, it turns the satellite, overshoots the retrograde marker, and then very slowly homes in, which is a problem because by the time it gets onto the marker the satellite is already firing its engine, and because its center of mass is slightly offset it never quite gets there, which then requires a lot more correction burns.

The satellite has reaction wheels and engine gimbal powerful enough to completely overcome the mass offset and keep pointing in one direction, it's just that the kOS "lock steering to ..." function isn't really taking full advantage of it.

Is there any way to fix this issue?
